Why tire circularity is becoming a structurally attractive platform for institutional capital — and what Greece’s feedstock infrastructure has to do with it.
Recycling, Repurposing & Reuse — Sirec Energy’s Fund Vertical
Over 1.5 billion tires reach end-of-life globally each year. For decades, the dominant question was how to dispose of them. That question has been replaced by a more valuable one: how to extract maximum industrial and financial value from a feedstock that never stops arriving.
The end-of-life tire (ELT) recycling sector is transitioning from a compliance-driven environmental obligation into a structurally attractive circular economy asset class. What was historically treated as a waste management problem is now recognized as a scalable industrial platform aligned with decarbonization policy, ESG capital flows, and material security strategies. The global scrap tire management market is projected to exceed $11.8 billion by 2030, signaling both the scale and the institutional relevance of what is happening.
At Sirec Energy, we have spent six years developing and investing in Green Transition infrastructure across Greece. Tire circularity sits directly within our Recycling, Repurposing & Reuse vertical — one of the six pillars of our Fund. What we see is a market at an inflection point.

The Feedstock Advantage No Other Waste Stream Replicates
Tire waste is non-discretionary. It accumulates regardless of economic conditions, consumer behavior, or commodity cycles. In Europe, Extended Producer Responsibility schemes have built collection infrastructure that now recovers approximately 95% of all end-of-life tires placed on the market. That is an operating system, already in place, already delivering consistent feedstock volumes to processing facilities.
This matters enormously for investment underwriting. The central risk in most waste-to-energy projects is feedstock security — will the supply materialize, at what cost, and for how long? In mature European ELT markets, that risk is structurally mitigated before a single financing discussion begins. For institutional investors, this translates directly into contracted, visibility-backed cash flows — the foundation of infrastructure-style return profiles.
Two Processing Pathways, Multiple Revenue Streams
Mechanical Recovery
This process involves shredding and grinding end-of-life tires into crumb rubber or rubber powder, recovered steel, and textile fibers. Key applications include:
– Rubber Modified Asphalt (RMA) – a mixture of ground tire rubber with asphalt that delivers proven economic, environmental, and performance benefits. Long-term testing demonstrates that RMA decreases CO₂ emissions and cuts energy usage over a pavement’s lifetime; enhances road performance with longer service life, better skid resistance, and significant noise reduction; and enables full substitution of SBS polymers in many formulations while complying with 2025 Green Procurement mandates.
– Tire Derived Aggregate (TDA) – a cost-effective infill for roadside embankments, retaining walls, and stormwater infiltration galleries.
– Sports & Recreation Surfaces – artificial turf infill, running tracks, playground surfaces and gym flooring remain strong demand segments.
– Molded Rubber Products – industrial mats, seals, gaskets and vibration isolation products increasingly integrate recycled content.
Chemical Recycling: Pyrolysis
Pyrolysis is a thermochemical decomposition process conducted in the absence of oxygen at temperatures typically between 400–700°C[1]. It operates at a categorically different level of value capture. The process yields the following indicative mass balance for a standard passenger tire:
| TIRE PYROLYSIS — INDICATIVE MASS BALANCE | ||
| Tire Pyrolysis Oil (TPO) | 35–45% | Energy-dense liquid fuel or chemical precursor. Primary revenue stream. |
| Recovered Carbon Black (rCB) | 25–35% | Industrial reinforcement material; direct substitution for virgin carbon black. |
| Steel | 10–20% | Clean metallurgical scrap with established steel mill markets. |
| Syngas | 10–15% | Recycled internally to fuel the reactor — delivers process energy self-sufficiency. |
Note: Indicative ranges only. Exact mass balance varies by feedstock type, tire composition, and process configuration. Midpoint yields sum to approximately 100%.
This mass balance creates inherent revenue diversification. No single output dominates, and the relative contribution of each shifts with market conditions – a structural resilience that single-product waste processing facilities do not have.
Strategic applications of TPO span: circular petrochemical feedstock (enabling manufacturers to meet mandatory EU recycled content targets); marine fuel compliance (subject to certification and Member State acceptance); carbon black feedstock for rCB production; and asphalt rejuvenator in civil engineering applications.
Market Scale
The global tire pyrolysis products market was estimated at $2.3 billion in 2024 and is projected to reach $4.8 billion by 2033, growing at 8.7% CAGR (CAGR (Grand View Research; directionally consistent with IMARC Group market sizing data).
TPO remains dominant in volume terms; rCB is growing fastest in value terms as certification-linked pricing premiums develop. The chart on the following page illustrates the product-level composition of that growth.
What’s Changed: The Regulatory Moat Is Now a Commercial Reality
European policy architecture has transformed regulatory compliance into a strategic financial asset. Three converging developments are creating sustained, structural demand for certified circular outputs — not as an ESG premium, but as a compliance necessity for buyers.
| FuelEU Maritime (live 2025) | Requires progressive GHG intensity reduction on ships in EU waters. TPO from certified circular processes qualifies as a lower-carbon fuel — subject to Member State acceptance — creating direct commercial incentive for shipowners facing EU ETS carbon costs. |
| EU ETS Carbon Cost Pass-Through | Buyers of virgin carbon black and conventional petrochemical feedstocks face escalating embedded carbon costs. Independent lifecycle assessment conducted by the IVL Swedish Environmental Research Institute found rCB production emits 79–84% less CO₂ than virgin carbon black — a figure corroborated by separate industry analysis placing the reduction at approximately 80%. This differential is increasingly reflected in long-term offtake pricing. |
| Recycled Content Mandates | Michelin targets 40% recycled & renewable materials by 2030, 100% by 2050. Continental already uses rCB commercially. Today fewer than 1% of global carbon black in new tires comes from recycled sources — illustrating the scale of the supply gap. |
ISCC+ certification transforms pyrolysis outputs from commodity waste derivatives into traceable circular assets eligible for regulated supply chains. Facilities without certification compete on price alone. Certified facilities compete on compliance value — a categorically different and more defensible commercial position.
ISCC+ certification also serves as the gateway to Green Bond and sustainability-linked financing, effectively decoupling a facility’s valuation from waste-sector volatility and reclassifying it as a producer of high-margin industrial assets.
Financial Performance and Risk Mitigation
A well-structured pyrolysis facility processing 40,000–50,000 tons per year in a European market with secured feedstock can achieve EBITDA margins in the 38–45% range under realistic operating assumptions. Returns in the 16–20% levered IRR range are achievable in the base case.
Getting to the upper end requires certified TPO offtake at petrochemical or marine fuel pricing tiers, rCB sales above commodity grade, and operational utilization above 82% by year two — all achievable, but not automatic. Any projection that assumes all three simultaneously from year one should be stress-tested.
- Revenue stabilization comes from long-term offtake agreements for TPO and rCB.
- Structural cost advantage accrues as ETS costs intensify — certified circular alternatives gain competitiveness embedded into pricing frameworks.
- Operational resilience is delivered through syngas recirculation, eliminating most external energy price exposure.
The cash flow floor is more defensible than typical waste-to-energy projects. The upside — certification premiums, carbon cost displacement, commodity optionality — sits above a relatively stable base.
The Greek Market: Where Infrastructure Meets Opportunity
>95% ELT recovery rate — one of the highest in the EU
Greece is not a market most infrastructure investors would identify instinctively for industrial pyrolysis. It should be. And we say that as a fund that has been investing in Greek sustainable infrastructure since 2021, with direct visibility across the waste and resource recovery landscape.
Eco-Elastika’s national collection network recovers over 95% of all end-of-life tires placed on the Greek market — confirmed in Eco-Elastika’s own operational statistics and one of the highest rates in the EU. The EPR framework has operated consistently and professionally for over two decades. Feedstock supply is an institutional-grade input: predictable, professionally managed, and contracted.
What Greece lacks is not feedstock — it is advanced processing capacity. Mechanical granulation and cement co-processing have been the dominant recovery routes. Across Europe, installed rCB production capacity stands at approximately 20,000 tons per year against estimated demand of 250,000–550,000 tons — a structural supply deficit that certified producers are only beginning to close. The transition to high-value circular petrochemical production is only now beginning in Greece, and the window to establish first-mover positioning is narrow.
Greece’s first large-scale industrial pyrolysis facility — targeting 45,000 tons per year, utilizing advanced technology from Pyrum Innovations AG — marks the country’s entry into this space. It establishes a directly replicable model for other EU markets where EPR infrastructure is mature, but advanced processing capacity remains underdeveloped.
Where We See the Opportunity
The combination of reliable feedstock infrastructure, regulatory-driven buyer demand for certified outputs, and significant gaps in advanced processing capacity across Southern and Eastern Europe defines a specific and time-bounded investment window.
The projects that will generate institutional-grade returns are not chasing the best technology — they are pairing proven technology with contracted feedstock, securing ISCC+ certification early, and locking in offtake with buyers who need certified circular supply to meet their own compliance obligations. The technology question has largely been answered. The execution and structuring question is where value is created.
Sirec Energy brings six years of investment experience in Greece, direct relationships across the domestic waste management and resource recovery ecosystem, and an active pipeline of opportunities within this vertical.
If you are an investor, industrial partner, or offtake buyer looking to engage with this market in Greece or across Southeast Europe, we would welcome a direct conversation.
